Abstract:

We examine some mathematical tools for dealing with ambiguous situations. The main tool is the use of non-standard logic with truth-values in what is called a locale. This approach is related to fuzzy set theory, which we briefly discuss. We also consider probabilistic concepts. We include specific examples and describe the way a researcher can set up a suitable locale to analyse a concrete situation.

En este trabajo se examinan algunas herramientas matemáticas empleadas para tratar situaciones ambiguas. La herramienta principal es el uso de lógica no estándar con valores de verdad en lo que conoce como un locale. Esta aproximación se relaciona con la teoría de conjuntos difusos, que se comenta brevemente. También se consideran los conceptos probabilísticos y se incluyen ejemplos específicos. Asimismo se describe la forma en que un investigador puede construir un locale adecuado para analizar una situación concreta.
